What is the fill time for the LiveO2-AC and Extreme O2?

For 10 LPM LiveO2-Adaptive Contrast and Extreme O2, the fill time is approx­i­mate­ly 1 hour when the sys­tem is set for fill.

When you fill the sys­tem be sure the slide con­trol is set to -O2. Note the posi­tion of the slide gate, which clos­es off the oxy­gen port. During fill this posi­tion pre­vents oxy­gen from escap­ing from the fill.

Position Slide Valve on -O2 set­ting to fill.

Also, the oxy­gen flow should be set to the max­i­mum flow of the con­cen­tra­tor. The ball float indi­ca­tor should be posi­tioned at, or slight­ly above the max­i­mum fill lev­el.
